To el! 'it-hom it may concern:

Be it known that l, Bumsms D. WASH- BURN, oiiioston, in the county of Suiioik etui State oii Massachusetts, have invented certain new end useful Ii'nprovcmenis in Blindiiinges, of which the foliowingds :t speciiicntion.

lihis invention has ihr its object to furnish e blind-hinge which shell be dura-ble :ind sinipie i u its soustraction, and essi ly manu factored and applied in position, and is on improvenieut upon the biindliiuge for which Letters Potent No. '151,942 Weregruntcd to me on the lith doy oi June, 187i.

The invention consists iu forming the hingearin, or part which connects Wit-l1 the ixed pintle, and the eibowplete ol seperate pieces of Wroughtiron, the erm portion being somewhat thicker than the elbow portion, sind provided with el letereihf-projccting lip, which lies upon seid elbow portion, and hes e flange which iits against the edge thereof, the two separate ports-that is, the elbowr and erm portious-beingunited by ineens of rivets, ell es more particularly hereinafter set forth.

in the accompanying drawings, Figure l is' ai perspective `view, representing my hinge es eppiied to e shutter. Fig. 2 is e perspective View of lthe hinge before being applied in position. Figli is :i detached View of the parts. Fig. 1i is a. section of an ongle-plete, representing the oouutersiink openings in the seme; and Fig. 5 is a, plan View of the hinge,

in the manufacture of wrought and sheet iron hinges heretofore generally practiced, the parts composing the hinge ere welded togetter, which renders it e diliicult tesi; to forni s. strong and neat hinge, es iiews and other incidental defects occur in the iron ot" which strich hinges are constructed ,f besides, the process of manufacture is Tory expensive when the parts are Welded together, es they must be heated to o. Welding heet after being cut, e iiiix eppliedfend e very careful manipulation performed, requiring greatskill.

in order to avoid the before-named defects and greet expense of manufacture, end facilitete end cheepen production, and to furnish s strong and durabie hinge, i proposed in my above-intentioned Letters Patent te construct my improved hinge with an elbow of wrought iron ind the hingeerm of cestiron., the two being united together by means of rivets; but, owing to the i'zuft, that the cest-iron erre must he constructed ol the best quality of ,inet-el zuid ot considcrztbe thickness, the coseof manuiiufiure Wes found to be 00 great, and the hinge ico heavy und clumsy.

.in order, therefore, te furnish a, hinge which sheii combine strength, lightness, and durebility, together with s, reduced cost of manu facture, i propose to construct the two separate parte Wroughi-irou--thet is, forming the angle-plete which is attached to the shufiier in one piece, and the erm which is attached to the fixed pinne in another piece, which is somewhat thicker than the elbow part, because oi the grenier strain to which it is subjected in supporting the Weight of the blind. It would, of course, not oe practicable to cut these two ports from :i single plate of metal.

As represented in the drawings, A designates the :ingle plete, which is formed of Wroughtiron, und is secured to the corner ci' the shutter c, to ,.iriice or stay the sume, end to support the iaingeerm B, which is likewise' constructed of Wrougiitiron, and is somewhat thicker than the elbow portion, as shown., SeidS ongle-pitite is provided with eountersunk openings on one side, or ou both, to eilow it to be reversed for use on right or ieft hand shutters. The hingeorin i3, which is made or formed in one piece, is eut or* otherwise formed from sheet er Wroughtinctul, with a. pintle-socket, C, et its outer end, sind e dowmverdly-piojectu ing lip, C', et the other, at right angle-s to the erm, seid lip overlapping a portion of the ingle-pitite for u, short distance, in order to more securely fasten the two parte together. The said. hinge-erm may oe mede straight or bent into an elbow form, according to the locution of the shutter and description of the ouiiding to which it is applied, a, straight erm being used when the shutter is not required to clem: obstructions onl the building, and en elbow-erin being resorted to when projections necessitate certain outward throw oi the shutter, 'iT-hepiotle-socketsmayelsobeicrmed on diiterent sides of the hinge-erm, es shown in the drawings, 'to euobie it to be used with right sind lett heed shutters.

In order to more securely unimi the two parts of the hinge together l inwrt nu utli` nary screw, G, through tlm anw into tht- WOOd-Work of llulQlinttt-r lwtu'cori thtrh vH. by whih the ports :iro hrlil fo; ;^th:. .miti screw serving thol douhlc pin-pmu 1' :iwf-i in; to bind the parts togethviI .nnl st-inring' thi; hinge to the shutter.
